I have been cutting for a while now and I find that the water needs to be changed about once a month. I am using disstilled water but I find that after a while it goes all gloopy so I have to chuck it away and replace. I have been wondering wether I should add something to it like anti-freeze to try to limit this happening.
I have been cutting 2 and 3mm thick acrylic and found that the finish of the cut edge is really good. I have been cutting 3mm acrylic on 10m/s and 11 on current.
I have been cutting some 0.8mm thick plywood but I have to do 3 or 4 passes to get a decent cut without excessive blackening of the ply. Cutting 3mm MDF gives good results. I use cereal box cardboard for my test cuts and that cuts really nicely. I have found that when cutting intricate letters I have to slow the speed down otherwise vibration in the machine makes the work move on the honeycomb resulting in scrap!
Before I cut anything I set the distance to the work using a digital readout vernier so that I get a good result.
THE BAD
I replaced the base plate with a sheet of plain aluminium and added stops to ensure the work was always at the origin. It now looks like one of the limit switches has moved as it does not go back to the origin correctly so now I have to work out where the limit switches are and how to adjust them!
